What is WHC?
WHC is a cloud-based phone solution that works via either Hosted PBX or Hosted SIP Trunking.
Hosted PBX
A completely digital and future-proof system. Your customers will connect digital phones, computers and mobile devices directly to the internet.
Hosted SIP Trunking
Replace ISDN and let your customers keep their on-site PBX hardware – so they can stagger or delay their eventual transition to all-IP.
For better teamwork, just add Webex
Expand your portfolio with WHC with Webex. Offer high-definition videoconferencing, shared digital spaces, instant messaging and file sharing – all in one scalable, cost-effective platform.
Add external calls to Microsoft Teams
Built for the channel market, WHC Teams Direct Connect lets you integrate WHC into Teams in a matter of minutes. You can even mix and match Hosted PBX, Hosted SIP Trunking and Microsoft Teams.
To get started with WHC Teams Direct Connect, your customers will need to already have Microsoft 365 and Microsoft Teams licences
